Technical Data
Dynamin, phosphorylated (Ser774)
Dynamin is a member of a group of nerve terminal proteins called dephosphins that regulate synaptic vesicle endocytosis. Cyclin dependent protein kinase 5 phosphorylates dynamin at Ser774 and Ser778 that are the phosphorylation sites on dynamin phosphorylated in vivo. Phosphorylation of these sites on dynamin is thought to play a key role in synaptic vesicle trafficking.

Suitable for use in Immunofluorescence, Western Blot, Immunocytochemistry and Immunohistochemistry. Other applications not tested.

Recommended Dilutions:
Immunofluorescence: 1:1000
Western Blot: 1:1000; Band at ~95kD. The labeling of the dynamin band in Western Blots of rat brain was blocked by the phosphopeptide used as the immunogen, but not by the corresponding dephosphopeptide.
Immunocytochemistry: 1:1000
Immunohistochemistry: 1:1000
Optimal dilutions to be determined by the researcher.

Positive Control:
Rat brain synaptosomal lysate

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Not Determined
Synthetic phosphopeptide corresponding to amino acids residues surrounding the phospho-Ser774 of human, mouse and rat dynamin.
Purified by Protein A and immunoaffinity chromatography.
Supplied as a liquid in 10mM HEPES, pH 7.5, 150mM sodium chloride, 0.1mg/ml BSA, 50% glycerol.
Recognizes human dynamin. Labels dynamin phosphorylated in vitro by Cdk5, but not PKC. Does not crossreact with other purified substrates of Cdk5 (eg. amphiphysin and synapsin). Species Crossreactivity: mouse and rat.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
